I'm having a problem doing a directory listing on a particular sftp server.
I'm not exactly sure what make the sftp server is but I get this when I log
in using FileZilla client, "Response: fzSftp started", so it could be a
FileZilla server. I'm not having any problems with other sftp servers.

I'm using the latest curl version and a recent libssh2 snapshot:

$ curl --version
curl 7.38.0 (i686-pc-linux-gnu) libcurl/7.38.0 OpenSSL/0.9.8y zlib/1.2.3.4
libssh2/1.4.4-20140922
Protocols: file ftp ftps http https scp sftp
Features: IPv6 Largefile NTLM NTLM_WB SSL libz

This is the command that fails and the output:

$ curl sftp://ftp3.xxx.com/ftp/ADAP323/bookings/ -u "XX:YY" --trace
/tmp/curl.trace -k
drwxr-x--- 2 ADAP323 FTPADM 8192 Sep 22 15:11 .
curl: (79) Could not open remote file for reading: Unknown error in libssh2
:: -37

The contents of /tmp/curl.trace is (with some anonymization):

I build libssh2 with: --prefix #{node.build.install} --with-openssl
--with-libssl-prefix=#{node.build.install}

and curl: --prefix #{node.build.install} --disable-ldap --disable-dict
--disable-gopher --disable-imap --disable-pop3 --disable-rtsp --disable-smtp
--disable-telnet --disable-tftp --with-ssl=#{node.build.install}
--with-libssh2=#{node.build.install}"

#{node.build.install} just expands to my install directory, e.g. /usr/local.

Let me know if you think this is a problem with libssh2 and I will try
their forum or if there is any other information that I could provide.

/Thanks
Emanuel
